## Script Injection

When Wails serves your `index.html`, by default, it will inject 2 script entries into the `<body>` tag to load `/wails/ipc.js` and `/wails/runtime.js`. These files install the bindings and runtime respectively.

The code below shows where these are injected by default:

```html
<html>
  <head>
    <title>injection example</title>
    <link rel="stylesheet" href="/main.css" />
    <!--     <script src="/wails/ipc.js"></script> -->
    <!--     <script src="/wails/runtime.js"></script> -->
  </head>

  <body data-wails-drag>
    <div class="logo"></div>
    <div class="result" id="result">Please enter your name below 👇</div>
    <div class="input-box" id="input" data-wails-no-drag>
      <input class="input" id="name" type="text" autocomplete="off" />
      <button class="btn" onclick="greet()">Greet</button>
    </div>

    <script src="/main.js"></script>
  </body>
</html>
```

### Overriding Default Script Injection

To provide more flexibility to developers, there is a meta tag that may be used to customise this behaviour:

```html
<meta name="wails-options" content="[options]" />
```

The options are as follows:

| Value               | Description                                      |
| ------------------- | ------------------------------------------------ |
| noautoinjectruntime | Disable the autoinjection of `/wails/runtime.js` |
| noautoinjectipc     | Disable the autoinjection of `/wails/ipc.js`     |
| noautoinject        | Disable all autoinjection of scripts             |

Multiple options may be used provided they are comma separated.

This code is perfectly valid and operates the same as the autoinjection version:

```html
<html>
  <head>
    <title>injection example</title>
    <meta name="wails-options" content="noautoinject" />
    <link rel="stylesheet" href="/main.css" />
  </head>

  <body data-wails-drag>
    <div class="logo"></div>
    <div class="result" id="result">Please enter your name below 👇</div>
    <div class="input-box" id="input" data-wails-no-drag>
      <input class="input" id="name" type="text" autocomplete="off" />
      <button class="btn" onclick="greet()">Greet</button>
    </div>

    <script src="/wails/ipc.js"></script>
    <script src="/wails/runtime.js"></script>
    <script src="/main.js"></script>
  </body>
</html>
```
